• Not logging in before pushing images, causing authentication errors.
• Choosing a repository name that is already taken.
• Forgetting to set the correct visibility (public/private) as needed.
• Not tagging the Docker image with the correct repository name before pushing.

bash

docker push myapp:latest
# Wrong: image not tagged with your Docker Hub username

docker tag myapp:latest yourdockerid/myapp:latest
# Correct: tag image with your Docker Hub username

docker push yourdockerid/myapp:latest
# Now push will succeed

Output

Error response from daemon: repository does not exist or may require 'docker login'
